Biden, who served as a senator for 36 years prior to becoming President Obama’s vice president, earned the nickname “Amtrak Joe” for his daily commutes between Washington and his home in Wilmington, Del.

That tradition went by the wayside in recent years, when Biden and his wife moved into the vice presidential residence at the U.S. Naval Observatory in Washington.

Biden last week revealed that he will work on foreign policy issues at the University of Pennsylvania and would continue his cancer “moonshot” initiative through a new organization, the Biden Trust.
